'.LINTIED.v BUBNISHD Ho Drawing. Application meld January This inventionis an improvement in embossed paper, and more particularly in metalcoated embossed paper. Y

/In my co-pendin application Ser., No. 2441 o f even date erewith, aprocess of treatingpaper is set forth, 4,wherein the paper is providedwith a metallic coating, having a very high luster, and a 'considerabledegree of iridescence. Substantially eve character of metallic powdermay be u with a basic solution, thereby lto impartto the paper thedesired tint, merely byadding the/powder. to the solution in the correctpro ort1ons. i

' T e com osition bearing the trade name ,argentine composed of a linelydivided ltin moss or sponge obtained from a tin so'- 'lution byprecipitation with zinc, is, not adapted for use with the basic"solution, since it must be applied with an adhesive, (usually starchpaste) Ia constituent which thebasic solution does not contain.

The inish'of paper coated with this composition is obtained byburnishing, and where burnishing is relied upon to impart the desiredfinish, metallic powders should be applied with an adhesive, since. whenthey are'applied in alcohol as a` vehicle, the

best eiects from burnishing do not obtain.

Such.l powders, namely argentine, alumigold, give very beautifuleffects, each in a s1n le color phase, and they provide a very desirableground-work for tintingwith various colors, when the tint is so appliedthat the sheenand luster o f the metal coating are visible' through theapplied tint. The-said embossing, and I have discovered t at verybeautiful eects may be obtained by tnting the embossed 4burnished apervwithy various colors, applied in the basic solution forming the sub'ectmatter ofV my no-pending applia cationv er. No., 2440 of even dateherewith,

and ysubjecting the paper while still wet to' a particulartreatment.`

The solution above mentioned' 1s composed of a hard resinrglac orshellac) a soft` paper is also well adar tedfor Bussum., Inssacmrsraus,va oonrounox or o g'entne treated face or faces, and while thetreatedsurface is still moist thesolution is worked by means (if reciprocatingbrushes.

This treatment apparently lessons the depth of the tint on the highportions of the em bossed Lsurface', and` in theffinished article givesvarious elects 4of .changi shadow and color, in accordance wit the di'rection of light, the shades blending sm'ootn` ly one into the other. f

The 'nted solution tinted coating. Such mperfection'sfwould p Shoals beapplica lightly, and the solution shouldibe relatively lshe e be vemhasized if the embossing were done I after ltie tinting." y ySubstantially any dye maybe used to `impart the desired tint to the par, either aniline or vegetable Dragons lood saffron and the like may-lbe plain paper, with ual advantage., The term light is'used to efinethe depth of the tint applied, and not the color, which may be Yof anyshade desired.

The basic, solution referred l. o holic solution of'a hard resin, asoftin or oil, with a dry wax, A suitable-ha resin used,l and. the jmethodmay be applied tothe tintingA of is lac, commonly known as shellac, andeither gum elemi or castor oil 'may bel used with the lac. Thev gumAelemi orf'castor oil f whenused acts as asoftenin agent `for the lac. Apreferreddry wax 1s stearic acid. The solution is prepared by dissolvingthe ingredients se arately each ln' a selected quantity of a cobol. `Thethree essential ,ingredients each in its`soluton', are lthen mixedto herin a,v selected ratio.

QA, re erred selection @of alcohol quantil'- ties or the initial.solutionfor theY several *l .1 l

ingredients is as "follows:

#1,'lac .60 lbs., alcohol 20 gal. #2, gum elemi 25 lbsQ, alcohol 15' #3,stearie acid 6 lbs., alcohol 12, g g

Heat may be usedwlth the first and second solutionsv to facilitate theaction if desired. When castor oil ,isused instead of gumelemi, it ismix-,d withyalcoholzin the proportion of abbot ico i 1lb.' of' theo1lto2 gal. ofthe( --alcoholr lf 'y The several' solutions, which havebeen des following proportions:

#3, 2 gal. With either of these basic solutions, the

selected color is mixed in the usual manner, s

sufiicient color being added to produce the tint desired.l
